Industrial chemical pumps

Parameters for selecting industrial chemical pumps

Industrial chemical pumps are specialized equipment designed for transferring various chemical substances, from aggressive and corrosive to highly viscous and hazardous. They are indispensable in chemical, petrochemical, pharmaceutical, food industries, and in the field of water treatment. These pumps are designed to minimize the risk of leaks and ensure the safety of personnel and the environment, making them crucial components in manufacturing and processing processes.

Key characteristics to consider when choosing a chemical industrial pump include the material of construction compatible with the transferred substances, performance, pressure, temperature range, and efficiency. It is also important to pay attention to the type of drive, flow control capability, and wear resistance. These parameters determine the durability and reliability of the equipment under intensive operating conditions.

When selecting an industrial chemical pump, the following parameters need to be considered:

• Material compatibility of the pump with chemical substances;
• Necessary performance to meet the required transfer volume;
• Operating pressure that aligns with system requirements;
• Temperature range suitable for the substances being transferred;
• Energy efficiency and operating cost-effectiveness.

Choosing a pump with the right characteristics ensures its long-term and safe operation, minimizing the risk of production accidents and process failures. Understanding the specific application and equipment requirements is key to the successful operation of industrial chemical pumps.

Types of industrial chemical pumps

Industrial chemical pumps are essential equipment for transferring various chemical substances, including aggressive, viscous, and hazardous liquids. They find wide application in the chemical, pharmaceutical, food industries, and other sectors where special reliability and process safety are required. Among the variety of pump equipment, several key types stand out, each with its own features and applications.

Centrifugal pumps and their features

Centrifugal pumps occupy leading positions among equipment for handling chemical liquids. They operate on the principle of converting the kinetic energy of rotation into liquid flow energy. These pumps are characterized by high performance, simple design and maintenance, and the ability to transfer large volumes at relatively low pressures.

Centrifugal pumps can be made from various materials resistant to corrosion and chemical exposure, making them an ideal choice for transporting aggressive substances. It is important to note that to ensure long service life and safety, centrifugal pumps should be selected considering the characteristics of the pumped liquid.

Screw pumps and submersible models

Screw pumps are a type of rotary volumetric pump, in which liquid transfer is achieved by the rotation of one or several screws. These pumps are ideal for transferring viscous fluids, those containing solid particles, and gas-liquid mixtures while maintaining a constant and smooth flow without pulsations. Screw pumps are also characterized by high reliability and durability, and their design allows them to work at high pressures.

Submersible pump models are typically used in conditions where the pump must operate directly in a liquid medium. They are particularly relevant for deep wells, tanks, or containers with chemical substances. Submersible pumps can ensure reliable operation even in aggressive and corrosive environments, thanks to the use of materials resistant to chemical exposure in their construction.

The choice of the type of industrial chemical pump depends on various factors, including the characteristics of the pumped medium, required performance, operating conditions, and economic considerations. A comprehensive approach to selecting pump equipment helps ensure the efficiency of production processes and personnel safety.

To ensure the reliability and durability of industrial chemical pumps, it is crucial to strictly adhere to operational requirements and conduct regular maintenance

The operational requirements for chemical pumps include several key aspects. Firstly, it is essential to strictly follow the manufacturer’s instructions and use the pumps only for the types of chemical substances they are designed for. Different types of pumps are engineered to work with specific aggressive mediums, and using them in unintended conditions can lead to rapid wear or even accidents. Additionally, it is important to monitor operating parameters such as pressure, temperature, and flow to ensure they stay within the specified limits.

Regular maintenance of chemical pumps involves a set of procedures aimed at preventing emergencies and extending the equipment’s lifespan. Key maintenance measures include:

• checking the seals and connections for tightness;
• replacing worn-out parts like seals and filters;
• cleaning and flushing the working elements from chemical deposits;
• lubricating moving parts if required by the pump’s design.

It is also important to regularly diagnose the equipment’s condition using visual inspections as well as more sophisticated methods like vibration analysis and thermography.

Preventing emergencies involves a set of measures to minimize risks associated with operating chemical pumps. A crucial element is training personnel on proper handling of equipment and chemical substances. Additionally, it is essential to have an emergency action plan and necessary resources in place for the containment and elimination of potential chemical leaks and spills.

Adhering to these principles of operation and technical maintenance will help ensure safe and efficient operation of industrial chemical pumps, reduce costs associated with repairs and equipment replacement, and prevent emergencies and negative impacts on the environment.
